It depends on how much time this person was sentenced to on the burglary of a habitation, which is the most serious charge here. Depending on the facts of the case (whether or not he was convicted of a 1st or 2nd degree felony), he could be exposed from 2-20 years in prison or 5-99 years. The other charges carry possible prison time as well.
POCS Charge #1 - Class A Misdemeanor, with up to 1 year in jail or up to 2 years of probation and a fine of up to $4,000.
POCS Charge #2 - State Jail Felony, with 6 months to 2 years in state jail or up to 5 years probation and a fine of up to $10,000.
Possession of Firearm by a Felon - 3rd Degree Felony, with 2-10 years in prison or up to 10 years of probation and a fine of up to $10,000.
Assault (Family Violence) - Up to 1 year in jail (or 2-10 in prison if he has previously been convicted of a family violence offense) or up to 2 years of probation and a fine of up to $4,000.
He is looking at the possibility of a lot of time and probation is probably not in play. He needs to get a good local defense attorney to discuss the likely outcomes in this case.
